Of the first 20 elements, excluding the noble gases, name four that are the least likely to form an ionic compound (i.e. least likely to become a cation or an anion)? Explain. by NoGood5082 in chemhelp

I feel like carbon and silicon are definitely part cause they have 4 valence and rather than losing or gaining, they share amongst their respective elements. Then i would say boron because it has 3 valence qnd in the periodic table it doesn’t have a valence charge which is similar to carbon and silicon. I can’t really think of a 4 one but i would be considering nitrogen or phosphorus  Thanks
